CIGABf-MACHINE RETURN-FEED '.'MECHAIIISIL Application tiled November 28,1928. Serial' No. 677,131.

To all whom t may concern."

Be it known that I, RUPERT E. RUnDELL, a citizen of the United States,residing at Brooklyn, county of Kings, and- State of New York, haveinvented a new and useful Improvement 'in Cigar-Machine 'Return- FeedMechanism, of which the following is a specification.

Thisinvention relates to a cigar machine return feed mechanism.

-In machines for makin fresh work or fresh bunch cigars, a eed mechanism1s employed which advances a sheet of filler material into the ran e ofaction of a charge severing device whic separates individual chargesfrom the sheet, thence into the range of actionof-a trimming mechanismwhich operates to trim the ends of the individual c arge, usually inserrated form. Heretofore, that part of the filler trimmed olf from thecharge; or in other Words, the filler trimmings, fall into a receptacleWhere they accumulate and from which they are removed from time to time.These filler trimmings, or a part ofthem, are used to augment the sheetof filler in the feed mechanism, but their distribution on the fillersheet has heretofore been irregular for the reason that they wererecovered from the receptacle at irregular intervals. Another objectionto the practice heretofore followed resides in the drying out of thefiller trimmin s in the receptacle, and this sometimes resulted in thebreaking u of trimmings into still'smaller particles o tobacco duringcigar bunch formation.

The main object of the present invention is the production of a returnfeed mechanism for cigar machines operating to return the fillertrimmings to entero-feed position as soon as they are separated fromsuccessive individual charges, so that the feed operator can at oncedistribute them on the ,sheet of filler in the feed mechanism' and,`

thus obtaineven distribution and avoid drying out of the trimmings. Withthis and other objects not speciiically mentioned in view, the inventionconsists in certain constructions and combinations which willl behereinafter fully described and then specifil cally ointed out in theclaims hereunto appen ed.

In the accompanying drawings, which form a part of this specificationand in which like characters of reference indicate the same or likeparts, Fig. 1 is a side elevation, partly in section, of a deviceconstructed in accordance with the invention; Fig. 1a is a detailed Viewof a modification of the returnfeed mechanism shown in Fig. l; Fig. 2 isa plan View, as indicated in the line 2 2, Fig. 1;. and`Figs. 3 ande:are respectively cross-sectional views taken on the lines 3-3 and t-t inFig. 1. In carrying the invention into effect, there is provided meansfor feeding ller to trimming position and there trimming it, and meanscoacting therewith to return filler trimmings to antero-feed positionwhere they may be readily distributed manually or automatically on the'sheet of filler in the feeding means. In the best constructions, thefeedving means and the return feeding means both include belts operatingintermittently and in synchronism. The above mentioned means may varywidely .in construction Within the scope of the claims for the par'-ticular device selected to illustrate the invention is but one of manypossible concrete embodiments of the same. The invention therefore isnot to be restricted to the precise details'of the structure shown anddescribed.

Referring to the drawings, 5 indicates generally a feed mechanismmounted on the rame' 6 of a cigar machine in connection with which it isused. As shown, the feed mechanism includes a feed belt 7 intermittentlydriven by. means of a ratchet mechanism 8 operating a belt drivingpulley 9. Coacting with the belt 7 are presser wheels 10 and aforwarding rake 11.V Also coacting with th'e feed belt 7, when thelatter is at rest, is a knife 12 the purpose of which is to severindividualcharges of filler from the advancin sheet on the feed belt.This knife is carried by a yoke -13 mounted on two posts 14, one oneither side of the machine, which posts are reciprocated by a bellcranklever 15, actuated by a cam 1 6, fast on a shaft 17 which is one of themain cam shafts of the cigar machine in connection with which the deviceis used. The yoke 13 also carries serrated knives 18, the function ofwhich is to trim the ends of individual charges of filler advanced bythe feedingmeansto trimming position. The structure so far described isold and well known in the art and since a detailed description of thesame is unnecessary to a full understanding of the present invention, itis omitted in the interest of brevity and clearness.

When an individual charge of filler reaches trimming position, its endsrest on swinging traps 19 fulcrumed at 20 to the frame 5 of the feedmechanism. These traps are normally held in the position shown in Fig. 3by means of springs 21, one end of each of which is hooked over a pin 22fast in the frame 5 before referred to. The other end of each spring issecured to one end of a lever 28 controlling the movement of a trap 19,and the opposite end of this lever carries a bowl 24 which normally liesin the path of a depending lug 25 carried by the yoke 13 before referredto. The yoke is shown in its uppermost position in F ig. 3. As itdescends so that the serrated knives 18 will engage the ends of thecharge of filler resting on the traps 19 and trim said ends in itsdescent, the lugs 25 engage the bowls 24 and swing the traps 19downwardlfy, as shown :in Fig. 4. A'Ihis opens the way or the fillertrimmings to fall on the up er run of a return feed belt 26, and the mecanism just described constitutes means con-y trolling delivery oftrimmings to the return in means.

e return feed belt 26 runs over and is driven by the feed belt 7 as thelatter runs over the driving pulley 9. The belt 26 also runs overpulleys 27, 28 and 29, the last named pulley being adjustable in a wellknown manner, as clearly shown in Fig. 1, for belt tightening purposes.

For the reason that the belt 7 is operated lintermittently and the belt26 is operated by the belt 7 over a portion of the perimeter of thedriving pulley 9, both belts are operated intermittently and insynchronism, and the filler trimmings transported from the positionbelow the traps 19 to antero-feed position will be delivered to areceptacle 30 in front of the pulley 27. The feed operator takes thetrimmingsfrom this'receptacle' and distributes them on the sheet offiller as she builds up the latter on the feed belt 7.

In the modification shown in Fi 1, the receptacle 30 is dispensed withan the belt 26 is carried up over a Small pulley 31 located over thefront end of the 4feed belt 7. In this structure, thefiller trimmingsare mesme automatically delivered to the feed belt 7 so that theoperator need place only the long filler thereon. y l As shown in Fig.4, the trimmings from opposite ends of a charge fall in separatepositions on the return feed belt 26. Means are provided and used insome constructions for gathering the separated filler trimmings inpredetermined position on the belt 26, and this means includes twodeliector plates 32 38, the lower edges of which touch the upper run ofthe belt 26 and deflect the oncoming separated lines and gather thetrimmings into one line of the saine, the osition into which thetrimmings are gat ered being determined by the form of the cigar themachine is making,-the trimmings going into that part of the cigar whichhas the greatest diameter. These plates .are mounted on a bar 34suit-ably supported by the frame 5 before referred to.

In view of the foregoing, a detailed description of the operation of thedevice is deemed unnecessary and is therefore omitted in the interest ofbrevity.

What is claimed is:

1. In a cigarv machine, the combination with means for feeding filler totrimming position and there trimming it, of means coacting therewith toreturn filler trimmings to antero-feedl position, said returning meansbeing intermittently o erative.

2. In a cigar machine, the combination with means for feeding filler totrimming position and there trimmin it, of means coacting therewith toreturn Filler trimmings to antero-feed position, both of said meansbeing intermittently 'operative in synchronism.

3. In a cigar machine, the combination with means for feeding filler totrimming position and there trimming it, of means coacting therewith'toreturn filler trimmings to entero-feed osition, said returning meansincluding an intermittently operating belt.

4. In a cifrar machine, the combination with means for feeding filler totrimming position and there trimming it, of means coacting therewith toreturn filler-trimmings to antero-feed osition, said returning meansincluding an intermittently operating belt and means for gatheringtrimmings in predetermined position on said-belt.
